Hitachi Data Systems, Caringo roll out storage upgrades

This week, Hitachi Data Systems (HDS) and Caringo Inc. made their object storage products originally developed for archiving more cloud storage-friendly with new versions of the Hitachi Content Platform (HCP) and Caringo CAStor software.

HDS rolled out Version 4 of its Hitachi HCP product with more cloud capabilities and a caching device called the Hitachi Data Ingestor (HDI) to speed the transmission of data from remote sites to and from a central HCP.

Caringo added multi-tenancy, dynamic caching, named objects, and domains and buckets to its latest version of CAStor 5.0.

Object storage systems that use rich metadata to keep information about context and content of data are becoming more popular as cloud storage systems, particularly in products such as EMC Atmos, HCP, DataDirect Networks Web Object Scaler (WOS), NetApp StorageGRID, and the Dell DX Object Storage platform that uses Caringo CAStor.

Data deduplication backup gets a few new twists

Arkeia Software and ExaGrid Systems this week came up with new approaches to data deduplication backup products. Arkeia added what it calls "progressive dedupe" into its backup software while ExaGrid Systems added an algorithm to broaden the applications supported by its disk appliances.

Arkeia launched Network Backup 9 with data deduplication technology the vendor acquired when it bought Kadena Systems last November. Arkeia did not have data dedupe in previous versions.

The Kadena technology uses progressive deduplication, which is different than the fixed-block and variable-block deduplication approaches most vendors use to identify dedupe data. Network Backup 9 is application-aware and creates a different size window depending on the application it is deduping. It takes a two-step approach, first looking for probable matches using a lightweight algorithm and then confirming the matches with a hash. Arkeia CEO Bill Evans calls this a sliding window approach, and claimed its method is faster than only using a hash.

Overland Storage launches high-availability SnapSAN iSCSI SAN

Overland Storage expanded its iSCSI storage area network (SAN) portfolio for small- to medium-sized businesses (SMBs) this week with the SnapSAN S1000 array, a 2U 12-drive modular array that can scale from 1.2 TB to 120 TB with disk expansions. The SnapSAN S1000 scales to less capacity than the SnapSAN S2000 that Overland brought out in February, but the new system includes a dual controller option for high availability.

The SnapSAN S1000's dual controllers support active-active failover and the devices have redundant, hot-swappable components. It also supports 10 Gigabit Ethernet (10 GbE) iSCSI and either SAS, SATA or Fibre Channel drives, according to Overland solutions marketing manager Joe Disher. It has snapshot capability and automatic disk spin down. The SnapSAN S1000 supports software replication, and Disher said Overland plans array-based replication down the road.

SNW Europe 2010 coverage: Power metrics, encryption, dedupe, object storage and more

SNW Europe 2010 is happening on Oct. 26-27, 2010, in Frankfurt, Germany. The latest data storage news and product announcements from the event are described below.

SNIA green storage metrics may measure space

The Storage Networking Industry Association (SNIA) is debating adding physical space metrics to its proposed Green Storage Initiative (GSI) power efficiency measurement specifications, said SNIA (Europe) Chairman Bob Plumridge at the organisation's Storage Networking World event in Frankfurt this week.

Emulex adds host-based encryption

Hardware card maker Emulex has announced the launch of two host-based encryption products for its HBAs, which are mainly sold to storage array makers. The two products are OneCommand Guardian, a software security product, and OneCommand Key Manager, an enterprise-class Key Management Interoperability Protocol (KMIP)-compliant key manager based on IBM Tivoli Key Lifecycle Manager technology. The two products can be deployed on servers, either on Emulex HBAs or as software.

Other storage news and product announcements from SNW Europe include the following: Exagrid announces new deduplication technology and CommVault gets Scality's object-based storage.
